英文摘要：

Plant modelling is one of the hottest researches in computer graphics. A digitalized algorithm is proposed to model garden plants. This algorithm realizes the simulating results by a digital representation of garden plants and four main simulation steps. It initializes the spatial-grid structure and contour structure of plants; plant＇s skeleton structure is generated by several steps：the growth area computation, the growth control, the energy computation of a grid and the new skeleton nodes update. It realizes the function of an interactive pruning and texture capturing and generation of a 3D mesh structure. The garden scene is established and rendered finally. By the algorithm in this paper plants can be generated with simple/complicated contour models. The experimental results indicate that this algorithm in this paper can realistically generate the garden plants, such as hedgerow and mosaiculture.
